So I'm having some knee issues doing any cardio, they seem quite sensitive which isn't normal, even with my normal activity. I think it may be nutrition related. Since going vegan I get very little calcium or vitamin D. Maybe I'm missing something else too. I try and eat healthy but I know I do not eat enough leafy greens. I try and have a small side salad here and there, but not enough and I really can't eat salad alot. I'm just not that kind of person. I don't have soymilk but maybe once a week, or calcium orange juice unless I have a smoothie (which I'm not having alot of since it's cold and I don't want cold breakfast). I really am just not a fan of eating greens. I can do kale chips, but eating it cooked or spinach, nope. Has anyone else had a similar issue since going vegan? I really can't think of what else could be going on. My shoes are fine, I'm not over doing it, ect..
